5, Claims. 1

The present invention relates to shower-cabinets and isparticularly directed to improvements to -the connection of the side and back walls of the shower cabinet to the receptor portion of the cabinet and to-each other.

It is the principal purpose of my invention to provide an improved shower cabinet wherein the sheet metal walls are so connectedwith each other and'with the upstanding metal flange of the receptor as to eliminate exposure of any of the raw edges of metal to water.

It-isa further purpose of the invention to provideconnecting means whereby the shower cabinet walls maybe mounted to the receptor flange and to the corner frames of the cabinet without using'metal screws and washers.

It is a further purpose of-the invention to provide a shower cabinet construction wherein the assembly of the walls on the receptor and the connection of the walls to each other may be accomplished with considerable saving of time and materials.

The nature and advantages of my invention will appear more zfully from the following description and the'accompanying drawings wherein a preferred form of the invention is shown. It should be understood however, that the drawings and description are illustrative only and are not to be taken as limiting the invention except insofar as it is limited by the claims.

In the drawings:

Figure l is perspective view ofa'shower cabinet embodying my invention.

Figure 2 is an enlarged fragmentary sectional view taken on th line 2-2 of Figure 1;

Figure 3 is a sectional view taken on the line 3-3 of Figure 2; and

Figure 4 is a fragmentary perspective view illustrating the manner in which a side wall is interlocked with a receptor flange.

Referring now to the drawings, Figure 1 illustrates a typical shower cabinet of the type to which my invention applies. A shower cabinet of this type usually comprises a receptor 5 that may be made of metal or of concrete or similar material with a metal flange cast integral with the concrete. In all such devices to which my invention applies there is an upstanding flange 6 of metal, and the side and back walls of the shower cabinet are secured to this flange. The critical points in a shower cabinet are the raw edges of the metallic walls and the meeting lines of the walls with each other and with the receptor. It is customary to provide a suitable surface on the metal walls to prevent their rusting or corroding. The raw edges however, do not readily take such protective surfacing and remaindiflicult from the standpoint of attack by water. In accordance with my invention I construct the upstanding flange S of the receptor 5 with its top edge bent over as indicated at 1 (see Figure 4). The flange is also bent downwardly as shown at-B and is provided with spaced gaps 9 through which corresponding parts provided on the side walls may pass to interlock with the flange. Thegaps Qare separated by-depending portions 1 c onthe-flange.

The showing in Figure 4 illustrates aside wall l l with its lower edgebent horizontally at l2 and then'upwardly to provide spaced lugs l-3-, which lugs are slightly smaller than the gaps ii. The lugs were separated by gaps Hl inthe upturned portion of the side wall. The gaps M are just large enough size to receivethe portions). The lugs l3 have the corners as shown at l5 to facilitate-the connection of a sidewall withthe flange 6. The connection is made in the following fashion. Assuming that the parts are in the position shown in Figure 4, the wall H is lowered until the part i2 thereof is substantially upon the ledge 5a of the receptor 5. Then the wall ll is moved toward the flange 6 until the leading edges N3 of the lugs 53 are in a position that upon slight movement of the side wall longitudinally of the flange, these will catch behind the portions l0. Then the side wall is moved horizontally in a direction parallel to the flange 6 to wedge the lugs it behind the portions Ill. This completes the connection of the side wall with the flange.

The back corners of the shower cabinet h'ave upstanding angle irons it that are adapted to seat down inside the flange 6. The portions? and 8 of the flange 6 are cut away far-enough to allow room for the angle iron H5. The angl ironoverlaps with the adjacent edges Ha and'lla of the side wall H and th back wall H. In order to close the joint at the angles where the side walls and theback wall meet I provide a series of spring clips 18 at each corner. These spring clips are offset as ShOWn at I9 and 20 so as to provide space between them and theangle iron It to receive the adjacent edgesof the walls. Preferably the clips [Bare welded to the angle iron 16. Each of the clips l8 has wing portions 2! and 22 extending inwardly and rounded as indicated at '23 and 24 to receive a projection 25 that is integral with a spring metal clip 26. The spring metal clip 26 is mounted within a curved corner cover plate 21. The clip 26 can be either in small sections welded at intervals along th cover plate 21 or it posite side edges thereof. Next the side walls II,

are interlocked with the receptor flange in the manner hereinbefore described and shoved rearwardly until the edge portions Ha are forced into the space between the clips l8 and the angle iron I6. The side Walls desirably have the front stiles 28 and 29 made integral therewith and the receptor flanges are cut away to pass the walls asshown in Figure 1. After the side walls are in place, the corner cover strip 21 with its clips 26 is placed against each back corner and forced into th corner until the projection 25 is interlooked around the portions 23 and 24 of the clips l8. The size of the corner cover plate 21 is made such that engagement of the clips 28 and i 8 forces the corner cover plate snugly against the side and back walls. The only additional assembly necessary is the securing of the head piece 30 at the top of the walls 28 and 29. This construction leaves the whole interior of the shower cabinet free of raw metal edges. It is also free of any screw heads or washers. There is no pocket in which the water can be dropped to cause corrosion the interior finish of the cabinet is fully protected. Assembly is easy and requires no special tools of any kind. Sealed joints are unnecessary since the very nature of the construction drains all the water that strikes the walls down into the receptor.

It is believed that the nature and advantages of my invention will be clear to those skilled in this art upon reading the foregoing specification.

Having thus described my invention, I claim:

1, A shower cabinet comprising a receptor having an upstanding flange along the back and side walls thereof and having ledges extending inward from said flange at said back and side walls, said flange having spaced downwardly extending lugs thereon, the free ends of said lugs being spaced inward from the flange, cabinet walls having outwardly turned lower edges resting on said ledges, and upstanding lugs on the said walls spaced therefrom and engaging between the lugs on the flang and the upstanding portion of said flange.
